PIN-OUT OF SERIAL CONNECTOR,FOR ALL VERSIONS (CN6)
Starting from series number 90000, every RM5 electronic coin validator ,with any configuration, is
equipped with a serial output: therefore if it is necessary to connect it or operate it via PC, it is
sufficient to connect the appropriate interface cable and build the desired software. The
transmission protocol is provided on request.
The validator responds to PC by sending the value of the coin introduced.

In those applications where an extra low comsumption coin validator is required, on request, it is
possible to use a special version with wake-up device.
This special coin validator is usually in a “Stop” status with reduced consumptions, lower
than 90 micro Ampere. Further to the introduction of the first coin, the equipment restores
its normal functions for a given time, then it returns to “Stop” status.
The coin validator is supplied with a jumper which MUST be used only during the programming
phase.
This jumper prevents the equipment from going into low consuption status and therefore it
can be adjusted or programming can be modified. Insert jumper between the two pins of
WAKE-UP connector as shown in the figure.
Remember not to leave it on, otherwise the equipment will never go to low consumption status and
as a consequence the battery will quickly run down.
